ESAW  Rayleigh Interferometer (MP-7604)For measurement of refractive index of liquids & gases. The interference fringes are magnified in the instrument to over 100mes by means of a cylindrical lens of the eye-piece which provides horizontal magnification. The fringes produced are sharp at the normal distance of distinct vision.It cons..

ESAW  Sagnac Interferometer (MP-7586)The Sagnac effect manifests itself in an experiments setup called ring interferometry. A beam of light splits and the two beams are made to follow a trajectory in opposite directions. To act as ring, the trajectory must enclose an area. On return to the point of entry, the light is allowed exit to the ap..
